Application filed January 9, 1822.

To all whom it 02mg concern:

Be it known that we, CoLIN SUTHERLAI-ID GRASETT and ANDREW Tunnorn CLARK, both subjects of the King of Great Britain, and both residing in the city of Toronto, county of York, Province of @ntario, Canada, have jointly invented certain new and useful Improvements in Advertising Mediums, of which the followingis a specification.

Our invention relates to improvements in advertising mediums, and relates more particularly to mechanically-moved advertising mediums, whether for indoor or outdoor use, and the objects of our invention are: let, to increase the publicity for the advertisements carried by the carrying means therefor, particularly in street cars and railway coaches and'the like, by moving the advertisements from one end of the vehicle to the other, and at the same time practically doubling the effectiveness of any given length of advertising space in vehicles of the character set forth; 2nd, to provide a particular carrier for the advertisementcarrying means which will permit oi? the removal and su stituti'on of any or all of the said advertise:nent-carrying means to permit of change of advertisements, and to associate with said carrier suitable driving; mechanism whereby the carrier will be preferably intermittently moved in order to intermittently shift the positions of the advertisement-carrying means; 3rd, to removably mount the advertisement carrying means, such as cards, so that they will be supported at their ends and sides and thus temporarily become part of the carrier itself, and in the following specification we shall disclose one species within our invention, and suitable driving mechanism, and what we claim as-new' will be set forth in the claims forming part of this specification.

Fig. l is an elevation of our preferred form of carrier, partly broken away, showin;- associated therewith the advertisementcarrying means, which are blank. Fig. 2 is a plan elevation of the carrier shown in Fig. 1, showing in addition plan views of certain pulleys and rollers coacting therewith. Fig. 3 is a side elevation of a suitable form of driving mechanism for the carrier, which latter is shown in cross-section. l is. in part, a vertical central longitudinal ection through certain operating parts of the driving mechanism shown in Fig. 0.

Serial. no. 527,881.

in: 5 is a longitudinal section, on an enlarged scale, on the line 55, 1. Fig. 6

is a cross-section, on an enlarged scale, on the line (S -6, Fig. 1. Fig. 7 is a longitudinal section, on an enlarged scale, on the line 7 '4', Fig. 1, and 8 and 9 are diagrammatic views of certain cams and rollers coacting therewith, to illustrate certain movements in the driving mechanism.

In the drawings, like characters of reference refer to the same parts. i In our preferred disclosure, our carrier comprises a pair of endless belts A, spaced apart and tied together by suitable removable means. These belts are preferably made of rubber compound, and imbedded therein to prevent the stretching of these belts, are metal wires C, preferably made of steel. The inner side of each belt is provided with a plurality of corrugations; D spaced equi distant, and substantially of the same width and height. These corrugations co-act with corresponding depressions l formed in the pulleys F and G, near the upper and lower ends thereof. F is the so drive pulley dgiven by any suitable mechanism, and G is the tail pulley. Since the carrier to be pr erably intermittently moved through certain given distances which will p tically correspond to the length of the advertisement-carrying means, positive driving means must be had, and the corrugations D and depressions E, are the preferred means whereby movement is transmitted from the pulley F to the carrier.

In order to support the carrier. the lower belt passes over flanges H at the lower ends of the pulleys F and G. Intermediate these pulleys area plurality of idler pulleys I, which are provided with the depressions E with which co-act the ribs B. These idlers are each provided with a flange J to give support to the lower bel A, or the lower side of the carrier, at the required positions, intermediate the pulleys F and G.

in order to hold the carrier against undue movement owing" to the lateral movement of the vehicle. rollers K are located preferably in pairs, and these rollers are positioned in respect of the idlers I so as to effect the purpose in view.

A Since it does not enter into our invention, we do not disclose any particular way of T and rollers K, nor the mounting the idlers J.

. referring to Figs. 2 and 5,

and according to the conditionsdetermining installation.

L are the advertisement-carrying means, for example, cards, and the preferred manner of mounting said advertisement-carrying means in respect of the belts A, is as follows: Associated with each belt A, and substantially of the same width, are a plurality of clamps 2, preferably made of rubber compound, and so associated as to be practically continuous. These clamps are for the purpose of clamping the sides of the advertisement-carrying means each to its associated belt A. The preferred manner of associating these clamps with the belts A, is as follows: Coupled to each belt A, and at the required places, are metal plates 3, secured each to its associated belt by any suitable means, such as rivets A. These plates are located on the outer side of each belt. Also coupled to each clamp 2 are plates 5, substantially of the same size as the plates 3. Any suitable fastening means is'used to couple the plates 5 in place, for example, the rivets 6. As will be seen upon the plates 3 and 5 lie in pairs at intervals. The sides of the advertisement-carrying means L are held between the plates 3 and 5, and of course are positioned against the plates 3 before the clamps 2 and their associated plates 5 are placed in position. Suitable fastening means is employed to couple the clamps 2 to the belts A, such as the following: Mounted in each plate 3 is a fiangp-provided stud 7, which projects beyond said plates, and

through slots 8 formed in the plates 5 and into pockets 9 formed in the clamps 2. Each stud is provided 'with a swivel head 10. The side of each advertisement-carrying means or card L is provided with a plurality of slots 11 shaped to more or less correspond to the shape of the swivel heads 10, as are also the slots 8. When the advertisement-carrying means L are placed in position as well as the clamps 2, the heads 10 are turned to lie transversely of the slots 8 and 11. The studs 7 are of course well-known and require no further description.

The plates 3 and '5 are of such width as not to interfere with the movement of the carrier around the pulleys.

The ends of the advertisement-carrying means preferably overlap as shown in Figs.- 5 and 7, and they are clamped together intermediate the belts A by the means used to tie these belts together: This means is preferably in the form of a pair of metal plates 12 and 13 somewhat wider than the plates 3 and 5, and intermediate said belts any number of the fastening studs 7 may be employed, and of course it will be understood that the plates 12 and 13, as well as the ends of the advertisement'carrying means will be slotted as already described in connection with the coupling of the sides of these advertisement-ca-rrylng means to the belts. Y

The plates 12 and 13 are located between their associated pair of plates 8 and 5 (see Fig. 5), and of course in the preferred construction illustrated the ends of the advertisement-carrying means are locateclbetween these plates. Because of the added number of parts at the ends of the advertisementcarrying means L, the studs 7 are somewhat longer than the studs 7.

Formed in each end of each clamp 2 are slot-sections, and these slot-sections, when adjacent clamps are placed end to end form slots 11' in which operates the swivel head 10 of each stud 7.

A pair of clamps 2 is of course used with each advertisement carrying means, and sufficient has been illustrated and described to show that any or, all advertisement-carrying means may be removed, as desired, and without much trouble, and replaced by like means carrying the required advertisement.

The corrugated portions of the pulleys F and Gr are of less diameter than therest of the pulleys, thus enabling the advertise mentcarrying means L to contact with the outer surface of these pulleys, so that the flexing thereof will be reduced as much as possible. The construction just described provides the said. pulleys with shoulders 15 at the top and bottom, so that the belts A will ride upon the upper shoulders, and below the lower shoulders. The upper shoulders 15 provide additional support to the belt in preventing sagging.

As before-mentioned, our carrier is preferably given an intermittent movement, and the distance the carrier is moved will'practically correspond to the length of the advertisement-carrying means, such as the cards L. We shall nowdescribe a convenient driving mechanism for the carrier, though of course it will be understood that any suitable driving mechanism may be used: in the examplary form of driving mechanism disclosed, the pulley F is loosely mounted on a shaft 16, mounted in suitable bearings. 17 is a pinion driven by any suitable means which is constantly in mesh with the toothed wheel. 18 which, together with the toothed wheel 19 is keyed to the sleeve 20 which is loosely mounted on the shaft 16. 21 is a toothed wheel keyed to a shaft 22, and constantly in, mesh with the wheel 19. Also keyed to the shaft 22 is a toothed wheel 23 which is constantly in mesh with the toothed wheel 24; mounted on the shaft 16. 25 is a cam coupled to the wheel 24:. The parts described are constantly in motion. 'VVhen the nose 26 of the cam 25 comes in contact with the roller 27 carried by the link 28, pivotally connected to lever 28 which is pivoted at 29, this lever is moved and through the medium of the pin operates'the lever 31 pivoted at 32 and so moves the'latch' 33 to the right. During this movement the tooth 34 of said latch depresses the spring-held bolt 35, and compresses the spring '36 mounted on said'latch and intermediate" a stop car ried thereby and the bearing'37 for one end of said latch. When the tooth 34L escapes the bolt 35, the spring 38 returns said bolt to normal position to be in the" path of movement of the tooth 34, and latch 33 after it has completed the described movement. Feathered on the sleeve 20 is a clutch-member 39, and associated with this is the usual runner 40 and bell-crank lever 41 which is pivoted at 42. This bell-crank lever is pivoted to the latch 33, and during the movement of said latch the clutch member 39 is moved to co-act with the clutch member 43 loosely mounted on the shaft 16 and firmly coupled in any suitable manner to the cam 44, which cam is suitably secured in any suitable manner to the upper portion of the pulley F. This pulley is immediately driven, and of course the carrier is given movement. Forming part of the cam 4A is a nose 4:5 with which co-acts a roller 46 mounted in a link 47 which is ivotally supported as at 48 by the bell-cran lever 49, in such manner as to have a limited range of movement. When the pulley F is started, the roller l6 occupies the position shown in Figs. 3 and 9 in respect of the nose 45, and as this nose escapes the roller 46, the same moves into contact with the lower surface of the cam, thus moving the lever 49 so as to bring its arm 50 above the latch 51 which is pivoted at 52 to the lower end of the bolt 35, and thus position the arm 50 so that when the nose of the cam 44 again comes in con tact with the roller 46, the arm will engage with the latch 51 thus moving the bolt 35 to release the latch 33, when the spring 36 will shift this latch and so operate the bell-crank lever 41 to throw the clutch out of engagement and so bring the pulley F and the carrier to rest.

The latch 51 is provided with a spring 53, which permits the arm 50 to move upwardly into. operative position.

The latch 51 is provided in any wellknown manner with means to co-act with the bolt 35 to limit its range of movement in- 25 are driven at reduced speed. The pulley F and cam :25 are made to rotate at the speed of the-toothed wheel 18.
